The article dedicated to the 90th anniversary of Gubkin University, discusses the main milestones of its foundation, associated with the name of its founder and first director, organizer of higher oil and gas education in Russia, Ivan Mikhailovich Gubkin. The data showing the contribution of Gubkin alumni to the development of the industry and oil and gas education, the achievements of the university in the implementation of its mission and the implementation of the program of development of Gubkin University as a national research university
Hypothesis of ring platform structures formation in oil and gas bearing provinces as a result of hydrocarbon gases explosions
The article considers hypothesis of ring platform structures formation as a result of deep gases explosions. Evidences of tectonic deformations in the rocks of the East Siberian and Siljan ring structures as well as their genesis are discussed
Modeling maturity of organic matter in source rocks of Silurian oil and gas source strata of southern Urals based on statistical processing of Rock-eval results
The article is dedicated to the statistical study of the organic matter of Silurian rocks, as well as modeling the generation of hydrocarbons in these source rocks of the southern Urals. This will make it possible to contribute to the whole picture of the formation of oil and gas accumulations, and also assess the impact of the candidate sources of hydrocarbons in the region. It will allow developing and expanding capabilities in solving urgent problems of localization and spatial distribution of hydrocarbons in traps, as well as revising the regional assessment of the region’s resources
Geochemical study of oil-bearing deposits of the Northern side of the Caspian basin
The article presents the results of the studies of the rock samples geochemical parameters from the wells drilled within the northern side of the Caspian depression and the zone of its juncture with the southern part of the Buzuluk depression. Potential oil and gas source strata were identified and characterized within the study area in the stratigraphic interval of the Middle Devonian (Klintsovski-Mosolovski horizon), Lower Carboniferous (Kosvinski-Radaevski and Bobrikovski horizons) and Middle Carboniferous (Vereyski horizon) systems. The type of organic matter and the degree of maturity of the deposits are established for each stratum. The results can be used in further studies of the hydrocarbon potential of the northern side zone of the Caspian basin and adjacent territories
Prediction of thermodynamic properties and phase behavior of reservoir fluids for the design of oil and gas fields
This article proposes methods for calculating the thermodynamic properties and phase equilibria of reservoir fluids based on both empirical multi-constant equations of state and theoretically based equations obtained in the framework of the statistical theory of associated fluid (SAFT). The article also proposes an alternative technique based on the author’s generalized PC-SAFT equation of state. The article presents the results of comparative calculations of the thermodynamic properties of model hydrocarbon mixtures, as well as real reservoir systems based on the proposed methods. The most accurate calculation of thermodynamic properties in the single-phase region was shown by the multiconstant model. In particular, the accuracy of density calculation is 3-4 times higher than according to cubic equations of state. When testing this model regarding the calculation of phase equilibria, limitations were established that recommend its use for light gas condensates, in which the molar mass of the residue does not exceed 140 g/mol and the relative density of the residue does not exceed 0,730. For reservoir fluids that do not satisfy the condition described above, it is proposed to calculate phase equilibria using a model based on the author’s PC-SAFT equation of state that can be used to calculate phase equilibria and near the freezing point of the mixture, where cubic and multi-constant equations can lead to nonphysical phase diagram
Mean Residual Life (MRL) of Gnedenko-Weibull Distribution. Estimates of Residual Life Time of Submersible Pump Equipment
The working life model (behavior model) of the object — the Gnedenko-Weibull distribution law is postulated. As a measure of reliability the article uses the mean residual time (MRL). For the Gnedenko-Weibull model, new representa-tions of the mean residual are obtained. The considered example of processing real operational data of pumps failures allows predicting the residual operating time of submersible equipment at the operational stage and can be used to assess the resource characteristics of the equipment

Ensuring reliable and safe operation of gas pipelines at Gazprom’s facilities is a priority. The results of studies of the impact of soil strength characteristics on the performance of thermomechanical drilling tools for use in the construction and operation of oil and gas pipelines in various natural and climatic conditions are considered. Based on the research results, practical recommendations for improving the technology of soil development with a drilling thermomechanical tool are given
Gubkin university: scientific and technical developments in the field of technical diagnostics of fuel and energy complex equipment and pipelines
The article discusses the history and current state of research in the field of technical diagnostics of equipment and pipelines of fuel and energy facilities, performed at the Gubkin Russian state University of oil and gas (NIU) from the 1960 to the present. The main scientific and practical results of the performed research are described, and the perspective directions of research performed at the university at the present time are considered. A multi-level system of personnel training in the field of technical diagnostics of gas transport systems is considered separately
Study of the effect of the actual bend radius of a conduit-conductor in the justification of feasibility of reconstruction of trunk oil and gas pipelines by the method of “pipe in pipe”
The article presents the results of the study of the influence of the actual bending radius of the pipeline conductor when justifying the technical possibility of performing reconstruction of main oil and gas pipelines on complicated sections of the route using the “pipe in a pipe” method. The results of calculating the radius of curvature of the pipeline-conductor section based on the results of measuring the spatial position of the route crossing the water barrier are presented. The minimum step between the measurement points of the spatial position of the Belousovo-Leningrad section of the pipeline with a diameter of 720 mm is set to estimate the radius of curvature when concluding that the “pipe-in-pipe” method can be reconstructed. Expressions are proposed for determining the effort of dragging the working pipeline into the conductor pipeline and the stresses that occur when dragging the working lash of the pipeline on straight and curved sections. It was found that the combined forces of dragging the internal pipeline for the main and backup threads create stresses that do not exceed the yield strength of steel, which indicates the technical possibility of dragging the projected gas pipeline at underwater crossings
Operational properties of multipurpose lubricants (MFS) which are widely repre-sented on the territory of the Russian Federation are studied. The penetrating ability, lubricating property and anti-corrosion ability of MFS are researched. A method for assessing the effectiveness of the composition of MFS in the processes of rust conversion is developed and tested. A wide range of MFS properties is shown depending on the problem to be solved
Development of models and algorithms of multi-criteria optimization of calendar planning of work of branched system of trunk oil pipelines
Various options were investigated and a combined scheme of compromise of criteria was proposed for the task of multi-criteria optimization of the operation of technological sections of an extensive system of trunk oil pipelines. An algorithm for searching quasi-optimal solutions was developed. This is based on the greedy search method with heuristics. The developed algorithm was tested on a branched trunk pipeline system, the results of testing were analyzed and conclusions were drawn on the applicability of the algorithm in the framework of monthly planning
Effect of preparation methods on catalytic properties of microspherical aluminosilicate cracking catalysts
Currently, catalytic cracking is the largest among the catalytic processes of oil refining to produce fractions of high-octane gasoline and diesel fuel. In the process of catalytic cracking of different types of technological implementation and instrumentation aluminosilicate zeolite-containing catalysts are used. One of the main ways to improve the efficiency of catalytic cracking units is the use of more active and selective catalysts. The article considers the influence of methods of preparation of microspherical aluminosilicate zeolite-containing cracking catalysts on their catalytic properties. It is shown that the catalytic properties of zeolite-containing cracking catalysts are significantly influenced by the method of introducing zeolite REY into the aluminosilicate base and the zeolite content. The obtained results are important in the development of technologies for the preparation of catalytic cracking catalysts
The article presents the results of studying the effect of changes in the technological parameters of the process of slow pyrolysis of plant biomass, such as the rate and final temperature of heating of raw materials, as well as the quantitative ratio of the obtained fractions. During the study of the obtained results, the dependence of the yield of products on the selected variant of the pro- cess was revealed, which made it possible to choose the optimal speed and the final heating temperature of the feed in order to obtain the maximum amount liquid product, with the possibility of its further use as a liquid environmentally friendly fuel component. The rate of heating of the feed was 5 °C/min, the final temperature of biomass heating was 500-550 °C, the yield of the liquid product at these parameters was 60-70 % by weight
Aqueous solutions of polymers are most common hydraulic fracturing fluid, however, when applied they deteriorate reservoir properties due to the formation damage with the remains of an undamaged polymer gel. This work describes studies aimed at creating a modified polymer-free fluid for hydraulic fracturing based on a viscoelastic surfactant of national production NEFTENOL VUPAV. To give the viscoelastic composition the necessary technological properties of the fracturing fluid (high viscosity, elasticity, proppant-support properties, etc.), a new activator reagent was proposed, which is an aqueous solution of salts of metals of different chemical valences. It has been established that the introduction of the developed activator into the composition of a polymer-free fracturing fluid makes it possible to create systems with high elastic and viscous properties with lower concentrations of the surfactant. A comparative analysis of the characteristics of the widely used polymer fracturing fluids and the developed composition based on NEFTENOL VUPAV with the addition of an activator has been carried out. It was found that the NEFTENOL VUPAV-activator system can be used as a potential proppant fracturing fluid
By assessing the linear crystal growth rate during recrystallization, it is shown that cement stone aging can be reduced by lowering the surface tension at the “growing crystals — solution” interface, and the diffusion coefficient, as well as the equilibrium solubility of the binder hydrated phases. The reasons for the fact that colloidal varieties of silica and acid silicates are not as effective in increasing the thermal stability of cement stone as those of crystalline are considered. Reducing the basicity of hydrosilicates to 1,5-1,8 is inefficient, as they are characterrized by high solubility and crystallization ability. The minimum dosage of siliceous rocks should be 20-30 %, since this allows achieving the basicity of calcium hydrosilicates close to 1. The search for mineral additives for obtaining a lightweight heat-resistant cement stone with mineral additives is justified
